+1 for Camera+, as well as how my Instagram is setup to do this.

+1 for Camera+. And dont miss that they offer a great analog filter pack.

+1 Yeah! Camera+ is exactly what I needed. Although Instagram can also save to photo library, but it also uploads on instagram servers (doesn't bode well when there is no signal in metro trains)

Another vote for Camera+ - the way you can take lots of pictures in quick succession and then later upload them all to the 'camera roll' makes it much more usable than the built-in camera app.
